Fifteen years ago, Jordan Passman had a simple idea: Help musicians make money. With the birth of Score a Score, what started as a digital marketplace for indie composers has grown into a full-service music agency with a client list that includes Apple, AT&T, McDonald’s, Pepsi, Activision and Netflix.

Score a Score has carved out a niche by streamlining and simplifying the process of providing original music for advertising, film trailers and brand campaigns. Its services span custom scoring, music supervision, sonic branding and curated playlists pulled from a catalog of tracks created by the company’s more than 400 composers from around the world.

Described by Passman — whose father, Don, wrote the industry bible All You Need to Know About the Music Business (11 editions and counting) — as “a music department in a box,” Score a Score possesses a unique strength in helping clients find the right sound quickly and seamlessly.
